IMPROVEMENT IN STOVE-PIPES AND GUARDS.

Specification forming part of Letters Patent No. 172,577, dated January25, 1876; application filed November 9, 1875.

To all whom it may concern.-

Be it known that I, ZIBA NIoKERsoN, of South Carver, in the county ofPlymouth and State of Massachusetts, have invented a new and useful orImproved Combined Stove-Pipe Guardand Gap or Cover; and I do herebydeclare that the following is a full, clear, and exact descriptionthereofiwhich will enable others skilled in the art to which it pertainsto make and use the same, reference being bad to the accompanyingdrawing. and to the letters of reference marked thereon, which form apart of this specification.

In the said drawing, Figure l is a frontelevation of the guard, showingthe funnelopening as closed by the cap or cover. Fig. 2 is a top view,with the cap or cover raised into a horizontal position, such as itassumes when a funnel or stove-pipe is inserted in the guard. Fig. 3 isa central and vertical section of the parts in position, as shown inFig. 2. Fig; 4 is a perspective view, showing the cap or part E indifferent positions.

The object of my invention is to provide a simple, cheap, and effectivedevice, which, when applied to an opening in the wall of a room, shallnot only serve to support a funnel or stovepipe, and prevent an undueradiation of the heat thereof through the walls of the guard, but whenthe funnel is removed from the guard the funnel-opening of the lattermay not only be automatically closed by its cover, but the device madeto serve as a most effective ventilator, which may be operated by thesimple attachment of a wire or device for moving and maintaining thecover at any desirable angle; and my invention consists in the peculiarconstruction, combination, and arrangement of parts of the device, ashereinafter described and claimed.

In the drawing, A denotes-the front plate of the guard, the same beingformed with a funnel-receivlng opening, a. B, O, and D are three plates,which extend inward from the plate A, and at or about right anglesthereto,

such plates constituting the walls of the guard, and, with the frontplate, being cast or formed in one piece. The top of the guard, or theportion in rear of the plate A, is formed open. E is the cap or cover,which is pivoted or hinged to the top of the lateral walls B and D, andin close proximity to the rear face of the front plate A, and so as toenable the Gover to be moved through an arc of ninety degrees, or fromthe position shown in Fig. l to that represented in Figs. 2 and 3. Thecover is constructed of such form and area as not only to close theopening in the plate A, but when raised into the position as shown inFigs. 2 and 3, to constitute the top wall of the guard.

By this construction and arrangement of the cover when the funnel isremoved the gravitating force of the cover will cause the latter to falland close the opening in the front plate, as shown in Fig. 1.

In order to retain the cover in position when closed, the lower plate 0is formed with an inclined lug or wedge, 12, having a notch, 0, as shownin Fig. 3, and the lower edge of the cover is made with a beveled edge,as shown at 0, so that when the cover is brought into impingement withthe front plate such beveled edge shall rest in the said notch, thegravity of the cover maintaining the said parts in connection.

I would remark that my improved device is so constructed that it may beplaced in ,the wall-opening, so that the cover may constitute the bottomor either side of the guard, instead of the top, as shown in thedrawing; but I prefer the latter method.

I do not claim, broadly, the combination of a stove-pipe thimble, and acap or stopper for the same, irrespective of their construction andarrangement, as I am aware that such is notnew. i

What I claim as my invention is- The combination of the guard, composedof the plates A, B, O, and D, and the cover E, pivoted or hingedthereto, the whole being constructed and arranged substantially as forthe purposes set forth.

In testimony that I claim the foregoing as myown invention I affix mysignature in presence of two witnesses.
